Well... can you possibly start over and explain things in more detail? Only
what you have provided is very little to go on, not to metion I am having to
now make guesses as to what you're using...

The "talk" command is/was used initially by BSD to allow users on a LAN to
talk to one another. But what you also need is talkd -- which is the remote
user authentication tool. "Talkd" has to be spawned from inetd if it is to
work, this something like the following [1]:

Sorry, but when you start demanding, my patience decreases. Don't do it. We
owe you nothing. I'm sure you mean well, but it doesn't come across as very
good when you think that you should be placed above all others for help. I
treat everyone with the same level of help, regardless of their 'issue'.

[1] This is from memory and so is possibly inaccurate. Either way, the entries
may well already be installed into the file: /etc/inetd.conf - and if no such
entries exist, those lines should be added to this file.
